The video, posted online yesterday, shows Stunt sitting in a chair dressed in a white bathrobe at the luxurious Jumeirah Carlton Tower hotel that costs £3000 ($5000 AUD) per night.

He claims his estranged wife Petra, 28, still loves him and will never agree to a divorce, before fighting back tears saying, "We have three beautiful children. We've been together for 11 years.

"I miss her terribly and I miss my children to death."

He's also concerned his daughter is old enough to hear some of the lies he claims are being spread about him.

"My daughter’s old enough to hear things. I don’t want her being made fun of because of what people hear in the papers. It makes me feel terrible," he says in the video, explaining that he's speaking out now because he thinks his former father-in-law is trying to "goad him" by leaking stories to the press.

"I've been falling for his antics," he says. "The truth is I'm heartbroken. I'm not some tough guy. I understand why the public don't like me. They see a d---khead. They're probably asking, 'Who's this jumped up w--ker?'

"But I’m not a bad person. I did the video because my wife is calling me a liar. The poor girl is traumatised."

In the clip Stunt describes the Ecclestone family as a "mixture of the Kardashians and the Mansons family", accusing Ecclestone of spreading lies.

"Horrific allegations have been made against me by an evil dwarf named Bernie Ecclestone," he says.

Stunt says he had no choice but to speak out after allegations made by Ecclestone to the Mail on Sunday that Stunt had once threatened to 'blow Petra's head off" during an argument, claiming the businessman is "impressed" by gangsters.

"He's impressed with those sort of people. I think he watches all those gangster films and had a big respect for them," Ecclestone alleged.

A recent court appearance over the divorce included a verbal spat during which Stunt called Ecclestone a "c---" before stomping out of High Court, The Sun reports, with the businessman seemingly making a gun gesture before barging into the billionaire and giving the finger to waiting photographers.

Petra Ecclestone moved out of the couple's £75m ($126m AUD) West London mansion in February.
